So I tried out my new Shark Navigator vacuum.....
....and of course I love it.
I'm tempted to say I wish I'd gotten the other model--the lavender one--because that one is lighter. My shoulder is still bothering me when I vacuum. But I think the swivel steering feature of the Pro model puts less strain on my shoulder, and that's good.
Switching from bare floor to rugs is much easier with the Shark than my Dyson. And, like everyone said, the suction is great. Cat litter scattered near the litter box is always an issue here, and the Shark made it disappear a lot more efficiently than the Dyson did.
Just two things I'd change:
One, I wish the cord didn't start out so low on the machine. I like to hold it as I vacuum, and it would be nice not to have to bend so low to pick it up. (I know, picky picky.....)
And I'd make the cord a little longer. The cord on my model is 30', which is 5' longer than the other model, but it's still not as long as the Dyson's. This just means I'll have to get used to moving to another outlet sooner; no big deal.
Thanks to those who recommended the Shark!
